As the perfect complement for Intel’s SAS-2 generation RAID cards, this twenty-four port expander card offers ultimate flexibility for architecting a high drive count (greater than 8 drive) storage solution in any sized system. The low profile height enables simple installation into a 1U or 2U system with a low profile chassis cutout. In addition, the MD2-compliant depth (6.6") fits in motherboards with heat-sinks that would interfere with longer add-in cards. In cases where an add-in slot is not available, the Intel RAID Expander Card RES2SV240 can even be mounted to a chassis wall or air-duct.

Excellent Performance Overall performance of the RES2SV240 is on par with Intel’s SAS-2 high port count RAID with transfer rates of up to 6Gb/s per port. While today’s high port count RAID cards typically include an expander on the card, a RES2SV240-based solution separates the expander from the RAID card for more system design flexibility.

Low-cost Alternative to High Port Count RAID Cards Provides a more economic solution that is similar to a 16 or 20 high port count card, but has more flexibility as the RES2SV240 can be teamed up with a wide variety of 4 or 8 port SAS RAID card/modules to offer features that are best suited to customer needs.

Inside-the-box Design Flexibility With a true MD2 form factor, this expander card is ideal for low-profile height and half-length adapter slots. In addition, the card design allows for mounting on chassis walls or ducting. Power can be obtained either from a PCIe slot or a power cable.

Rating: 5/5AmazingCard

Pros: It just worked. I have an ESXI VM with passthrough to a IBM M1015 card. Adding this card to the mix required 0 software changes on my part.

Cons: As others have noted, the 'installation guide' is a joke. I guess the thought process is if you buy a card like this, you most likely know what you are doing. Not worth losing an egg over.

Other Thoughts: Improved installation guide for a IBM M1015: Use one of the provided SAS to SAS cables to connect the SAS slots closest to the bracket on this card and the M1015. Use the other slot on the m1015 and the 5 remaining slots on this card to connect 24 drives using those SAS to 4xSATA cords. (1+5)x4 = 24. Math.

One of the reviews suggests that thing overheats. I preemptively through a COUGAR CF-V12H at this thing.

Other Thoughts: The instructions explain how to install the device into your motherboard in but it doesn't explain how to connect it to your SAS card with enough detail. The diagram has a lot of arrows and boxes of text, but it's not at all technical. You receive two short SAS cables which you expect to go between the expander and the controller, but the guide doesn't say to connect one or two if you're going to two hotswap backplanes. When the unnit doesn't work, calling Intel is useless as their overseas technical support representatives aren't so technical and their advice when things don't work is to flash upgrade your hardware. "Does this device even have a flash upgrade?" "I don't know... let me check." That certainly gives me confidence.

I suggest utilizing a controller from a manufacturer with more than two ports if you need more than 8 drives expanded.

Rating: 5/5Solid Expander

Pros: This expander has been working solidly in my storage server for several months helping to server up iscsi to my esxi hosts. Note as other have mentioned this doesn't have any controller capabilities. The main reason I'm writing this review is I have an Areca 1880xi and I couldn't confirm it would work with this would work with my Raid card.

I heard of people running into difficulties with some Areca cards and this expander especially if the have other expanders in the unit. In those cases their raid cards will not pick this expander up. That said, I have run into no issues.

Rating: 5/5Nice Extras

Pros: Awesome performance and ability to mount nearly anywhere. The power connector on the top can be used instead of plugging the card into a slot, but using a slot is generally easier if one is available.

Cons: None thus far.

Other Thoughts: I would like to add that despite the newegg image showing only the card, the box it arrives in contains both a low profile and full height bracket (full height installed by default) and also comes with 6 SFF-8087 to SFF-8087 cables (2 short, 4 long) just as the Intel documentation says it should.

Additionally, there are only 6 connectors on the card, there is nothing additional on the back. One or two connectors can be used to connect to your SAS card, which leaves either 4 or 5 connectors open for use. Using two of the connectors would only really be necessary if you're pushing the interface to its bandwidth limits/chaining cards together for ridiculous numbers of ports.
